350+ cfm Dust Extractor / HEPA Vacuum
The 350+ cfm dust extractor represents the highest-capacity class of HEPA vacuum equipment, engineered to maintain dust-free operation of large planetary grinders, shot blasters, and multi-head scarifiers. This class delivers airflow from 350 to over 1,300 cfm, far exceeding the suction demands of heavy concrete prep equipment. All machines in this band require 240-volt single-phase or three-phase power, reflecting their industrial duty cycle and motor size.

Spécifications clés
| Spécification | Plage typique | Signification |
|---|---|---|
| Airflow capacity | 350–1,320 cfm | High-volume suction maintains negative pressure at large tool shrouds and multiple pickup points. |
| Power requirement | 240 V single-phase or three-phase | Larger motors and multi-stage turbines demand voltages beyond standard 120 V circuits. |
| HEPA filtration | 99.97% @ 0.3 micron | Captures respirable crystalline silica and combustible metal dust to regulatory standards. |
| Filter area | Large pleated or cartridge banks | Extended filter surface area sustains high airflow without rapid pressure drop. |
Comment choisir
This class is specified when dust extraction must keep pace with planetary grinders 20 inches and larger, shot blasters exceeding 15-inch blast width, or simultaneous operation of multiple handheld tools. The 150–350 cfm Dust Extractor / HEPA Vacuum handles most single-operator grinding and scarifying work and requires only 120 V power; specify that class unless the tool manufacturer explicitly calls for airflow above 350 cfm or the job involves multi-head or ride-on concrete prep equipment. No higher-capacity class exists in the standard ladder; applications exceeding 1,300 cfm typically move to stationary industrial dust collection systems with ducted infrastructure.
Ce que cette taille peut gérer
- Dust-free operation of a 27-inch planetary grinder removing epoxy coatings in occupied spaces
- Shot blasting bridge decks or parking structures with ride-on equipment requiring continuous high-volume extraction
- Multi-head concrete polishing with simultaneous dust capture from all grinding plates
- Silica-compliant demolition of reinforced slabs using large scarifiers in enclosed areas
- Industrial floor prep where OSHA Table 1 compliance mandates verified airflow above 300 cfm
- Connecting multiple medium-duty grinders to a single extractor on linear production work
Sécurité et opération
- HEPA filters and collection bins require disposal as hazardous waste when contaminated with crystalline silica or lead paint dust
- Static electricity buildup in large-volume airflow paths demands grounding; some models include conductive hoses and grounding cables
- Operators confirm filter differential pressure or indicator lights before starting attached tools; clogged filters cause motor overheating
- Explosion-proof models or conductive collection bins are specified when vacuuming combustible metal dust (aluminum, magnesium) per NFPA 652
Transport et logistique
- Most units ship on wheeled bases with large-diameter casters for floor-level maneuvering; trailer transport not typically required
- Weight and bulk often necessitate liftgate delivery or loading dock access; models exceed 200 pounds in many cases
- Drum or bin capacity and filter housing size may require disassembly or tipping for doorway clearance
Alimentation
- 240-volt single-phase or three-phase connection; generators must deliver clean sine-wave power to protect multi-stage motor controllers
- Dedicated circuits and appropriate amperage breakers required; inrush current on startup can exceed 30 amps on larger models
- Extension cords must meet voltage drop limits for the motor horsepower; undersized wire causes overheating and nuisance trips
